Nearly two dozen immigrants--some as young as 13--who were promised a new life in the U.S. instead found themselves enslaved in a prostitution ring, the FBI said. Five members of the Cadena family of Veracruz, Mexico, were charged with multiple counts of smuggling immigrants and holding them prisoner as prostitutes. Rogerio Cadena, 51, was arrested in Fort Myers in front of one of his alleged brothels. Authorities are still searching for the other four suspects. The brothels, catered exclusively to Latino migrant workers, according to the complaint.
